Note: CRC Cyclic Redundancy error verification Calculation MethodThe CRC-16 (Cyclic Redundancy error check) generates the CRC-16 validation byte as follows:(1) load a 16-bit register. All digits are 1.(2) The high byte of the 16-b
In the Drive life or manual installation drive, sometimes there will be "data error (cyclic redundancy check)" prompts, this situation is mostly due to hard drive bad road caused by errors, the following small series to tell you how to solve.

have been wrestling with a CD these days, because some of the data on the CD can not copy, always appear "cannot Replicate: data errors (cyclic redundancy check)" This error, the Internet to find a lot of ways, said with WinRAR, said with data recovery, said with IIS rack Server breakpoint continued transmission, basically not a reliable, Finally found a way to s
Cyclic Redundancy check Cyclic Redundancy test is a set of verification codes based on data computing. It is used to check whether the data is changed or transmitted incorrectly during transmission.Algorithm principle
Assume that 15-bit binary information G = 101001110100001 needs to be sent during data transmission. T
I. INTRODUCTION of CRCFirst here is what is CRC: Cyclic redundancy Code Check English name is cyclical redundancy check, referred to as CRC, it is the use of division and the remainder of the principle of false detection (error detecting). In practical application, the transmitting device calculates the CRC value and s
Today began to study the Redis source code of some of the tools of the implementation, tool class in any language, the implementation of the principle of the algorithm should be the same, so you can take this opportunity to learn some of the more classical algorithms. For example, I see today the CRC cyclic redundancy check algorithm and rand random number generation algorithm.

Today began to study the Redis source code some of the tools in the implementation of the tool class in any language, the implementation of the algorithm principle should be the same, so you can take this opportunity to learn some of the more classical algorithms. Like I see today. CRC cyclic redundancy check algorithm and rand random number generation algorithm.
CRC algorithm full name
calculating cyclic redundancy codes
In Description computer network, cyclic redundancy code is used to verify the correctness of the data. The principle is that the sender calculates the cyclic redundancy code of the binary data
5.3.2 cyclic redundancy check and error check plan
The parity check code (PCC) introduced in the previous section can only verify one error. The cyclic redundancy check code (CRC) described in this section has higher
reduce a portion of the remainder by one person. The principle of Shang Shang is: When the first part of the remainder is 1 o'clock, Shang Shang 1; When the first part of the remainder is 0 o'clock, Shang 0. When the number of bits of a partial remainder is less than the number of bits of the divisor, the remainder is the last remainder. 1 1 1 0────────1 0 1 1)1 1 0 0 1 0 0 -1 0 1 1 ────── 1 1 1 1 -1 0 1 1 ────── 1 0 0 0 -1 0 1 1 ────── 0 1 1 0 -0 0 0 0
In industrial environments, electronic systems usually work in extreme temperature conditions, in an electronic noise environment, or in other harsh conditions, and whether the system works normally under such conditions is crucial. For example, if the data sent to the DAC controlling the machine arm location is damaged, the machine arm will move in an unexpected direction, which is not only dangerous, but also costly. Imagine what would happen if a machine arm hits a new car on the production l
Phpcrc32 calculates the 32-bit CRC (cyclic redundancy check) and crc32crc of the string. Phpcrc32 calculates the 32-bit CRC of a string (cyclic redundancy check) and crc32crc. note: in this document, the www.manongjc.comarticle499.html phpcrc32 function is used to generate the 32-bit CRC (
The CRC cyclic redundancy check algorithm is a hash function that can generate a fixed number of bits based on data to verify the errors that occur after data transfer/save, or to verify the integrity of the data, such as compressed files.The resulting hash value is computed and appended to the data before it is transmitted or stored.The general cyclic

Cyclic Redundancy check (CRC) is a data transmission error checking function. It computes the polynomials of the data, attaches the obtained results to the back of the frame, and performs similar operations on the receiving device.AlgorithmTo ensure the correctness and integrity of data transmission. If CRC verification fails, the system cop
